9 Claims.

My invention relates to tanks, and more particularly to tanksrespectively adapted for aging and for fermentation, in the productionof beer.

An important object of my invention is the 5 provision of a beer' tankwhose body will withstand without distortion the relatively highpressures encountered in the brewing of beer.

Another object is to provide a continuous 1inving for such a beer tank,which will not crack lo under such pressure and yet will conform to anyinequalities in the inner surface of a concrete tank.

A further object is to provide efficient means for holding such a liningin place in a tank of D the character mentioned.

The invention also comprises novel details of construction and novelcombinations and arrangements of parts, which will more fully appear inthe course of the following description.

20 In the drawing, like reference characters designate similar parts inthe several views.

Figure 1 is a vertical section of an open tank embodying certainfeatures of my invention, taken on the line I-I of Figure 3.

Figure 2 is a vertical section of a closed tank embodying certainfeatures of my invention.

Figure 3 is a horizontal section taken on the line 3-3 of Figure 1.

Figure 4 is an enlarged section taken on the line 4 4 of Figure 3.

Figure 5 is an enlarged section similar to Figure 4, showing a modifiedholding device, taken on the line 5--5 of Figure 6.

Figure 6 is a section taken on the line 5--6 of Figure 5.

Figure '7 is an enlargement of the drain ernplcyed in both the open andclosed tanks.

Referring more in detail to the drawing, the reference numeral 8generally designates an open concrete tank, consisting of a shell ofconcrete and a lining II. The shell comprises walls 9 and a floor Illand the lining is preferably of vulcanized rubber that is acidproof andimparts substantially no taste to the beer. Two forms 45 of mechanicalfastening devices have been shown in the drawing, for fastening thelining in place. The form illustrated in Figures 1, 3, and 4 comprises abushing I2 embedded in and extending transversely through the concretewall 9 of the tank. The inner surface I3 of the tank wall 9 has arounded depression I4 disposed at the inner end of each bushing I2.Embedded in the floor I of the tank is an acid resistant drain nipple Icomprising anges I6 and II at the inner and outer surfaces I8 and I9 ofthe floor Il). The nipple is threaded at for connection with a drainconduit.

The rubber lining II completely covers the inner surfaces I3 and I8 ofthe walls and floor, whereby to keep the beer away'from the concrete.

The lining carries bosses ZI that conform with and t in the depressionsI4. Bolts 22, whose heads 23 are embedded and vulcanized in the bosses 2I, project through the bushings I2. Nuts 24 are screwed on the threadedShanks of the bolts 22, whereby said bosses are drawn into theirrespective depressions to hold the lining tightly in place. The boltheads may be slotted, as at 25, into which rubber may flow to aid inpreventing the bolt heads from turning in the bosses 2 I.

An annulus 26 of acidproof material is bolted to the flange I5, pinchingthe rubber lining II therebetween, whereby to provide a fluid tight fitaround the drain nipple.

The lining II is lapped around the top edges of the walls of the opentank 8, as indicated at 2T. A hoop 28 extends around the periphery ofthe tank, clamping the edge of the lining in place by means of bolts 29embedded in the concrete, and nuts 33 on the bolts.

A closed tank 3l, embodying features of my invention, consists of walls32, a top 33 and a floor 34. A manhole 35 provides access to theinterior of the tank for cleaning, etc. Suitable connections may beprovided to and from both the open and the closed tanks, and suitablevalves may be provided in such connections. Since such connections andvalves per se form no part of my invention, illustrating and describingsame seem unnecessary.

For holding a lining 3B in place in the closed tank, a modifiedconstruction of fastening device 3l has been shown in Figures 2, 5, and6. This device consists of a stirrup member 38 and a hook member 39. Thestirrup members are mounted in sockets 40 at the inner surfaces 4I ofthe closed tank. -Bolts 42 embedded in the concrete walls 32 and top 33hold the stirrups in place in the sockets, through the intermediary ofnuts 43.

Each hook member comprises a foot 44 vulcanized in a boss 45 on theouter face of the lining 36. An offset arm 45 on the hook member engagesunder the stirrup member 38.

It is believed clear without further illustration that a clamping ringmay be placed around the manhole 35 similar-.to the annulus 26. It isalso to be understood `that the bolts 22 or fastening devices 3l may bedisposed in staggered relationship, and that either mechanical fastener,22 or 3l, may be used for the lining of either the closed or open tank.

The use ofmy construction is thought obvious. The concrete tank 3| hassuflicient strength to hold relatively large quantities of liquid andsufficient rigidity to resist distortion when conning the relativelyhigh pressures produced in beer aging (e. g., eleven pounds pressure).Furthermore the rubber lining not only protects the beer from thesolvent elements of the concrete, but

is flexible and is of relatively soft, resilient ber, which conforms toandcompensates forinequalities in the inner surface of the concrete.

the inner surfaceof aconcreteshell, it is pref# erable tovulcanizetheilining inlplace, in order that rubber of the lining may newinto the usual f Y Vvoids in the surface of concrete; By this means,

permanent bonds Yare made lat a pluralityiofl points, vthus securelyholding the liningvin-position.'V l Y Y In applying. the lining totheclosed top tank,
